Original no. 1,810,047, dated December 7, 1926, serial No. 122,599,filed July 15, 1926. Application m reissue filed March 10, 1927. SerialNo. 174,343.

My invention relates to pressing machines,

particularly to pressingmachines of the type known to the trade as valvein head machines, wherein a heating medium such as steam is admittedinternally of an upper pressing element or'head, having a perforated.face plate covered by a cloth and which is arranged for rockingmovement downwardly against a lower pressing element for pressingmaterial therebetween.

The primary object of the invention is the provision of an attachmentfor such machines, wherein by use of the attachment, a valve in headmachine may be converted into one of the type known as hot headmachines, wherein the upper pressing head is provided with a solid faceplate heated by steam from within the head. I

A further object is the provision of a presser plate member adapted fordetachable engagement over the movable presser element of a pressingmachine.

A still further object is the provision of a presser plate attachmentfor the movable presser element of pressing machines, which,

in addition-to accomplishing the above objects, may he employd as areplacement unit for the movable presser head of machlnes of the hothead type.

With these and such other objects in view as will be apparent from thedescription, my invention resides in the novel construction, combinationand arrangement of partshereinafter described and claimed, andillustrated in the accompanying drawings, wherein is shown one practicalembodiment of the principles of the invention. 1 is an elevation of thehead portion of a conventional pressing machine with the .attachment inservice position.

Fig. 2 is a bottom perspective of a presser plate attachment constructedin accordance with the principles of the invention.

' The attachment comprises a fiat metal plate 10, preferably ofaluminum, formed of the same configuration as the face of an upper,movable presser head 11 of a pressing machine of conventionalconstruction havin a; lower, stationary, horizontal presser hea 12arranged on the pedestal support 13.

The opposite side edges of the plate 10 are formed with upstruck,integral flanges 14 arranged longitudinally thereon at spaced intervals,with the u per edges of the flanges being rolled inwar y as at 15 toform bearings for a substantially U-shaped brace rod" 16 disposedtherethrough and. extending along each side edge of the presser plateand around the narrowed end thereof.

The larger end edge of the plate 10 is formed with a pair of flanges 17similar to the side edge flanges 14, and the free ends of the rod 16 arepassed through the rolled bearings 18 and bent outwardly back uponthemselves to form handle portions 19 at the larger end of the late. Theside edge anges 14 may be slightly inwardly inclined to provide for aspring tension which insures a frictional engagement of the'flangesagainst the side edges of the presser head 11 when the plate is attachedthereto, as shown in Fig. 1. A plurality of flexible, resilient elementssuch as re- .tracting spring coils 20, provided at each end with hooks21, are disposed over the topof the presser head 11 with the hooksengaging the rod 16 at opposite sides of the plate attachment, therebyinsuring a positive means for retaining the plate 10 in service positionwhen attached.

In applying, the handles 19 are grasped and hea of a pressing machine,with. the bend of the brace rod 16 abutting the reduced end of the head.The handles are then moved against the large end of the head to engagethe flanges 14 over the sides of the head. By movin the handles in adirection to se arate them t e op osed gripping portions or anges 14will be orced apart to allow the attachment to be readily applied orremoved. The top fastening elements 20 are then applied and the plate 10is drawn over the movable presser the attachment is ready for service.It will be obvious that heat applied to the presserhead 11 renders theplate 10 an eflicient hot presser plate, converting a valve in head mainthe structural details as will fall'within the scope of the invention asclaimed. I claim Y t 1. .A presser head attachment for movable headpressing machines, com rising a flat metal plate shaped to the conguration of a presser head, a series of spaced, upright 'fianges formedintegral with the side edges of said plate, said flanges being tensionedby inward inclination for gripping engagement over the sides of apresser head, bearings formed on the upper ends of said flanges, and ahandle member received through said bearings for application ofsaidplate to a presser head. t

2. A presser head attachment for movable head pressing machinescomprising a plate, a series of spaced inwardly directed flanges formedon the plate and adapted to engage the sides of the presser head, andresilient members connected to the flanges and engageable over the topof the head for connecting the plate to the head.

3. A presser head attachment for movable head pressing machinescomprising a plate, a series of inwardlv directed flanges formed on theplate and adapted to engage the sides of the presser head, and meansconnected to the flanges and engageable over the top of the head forconnecting the plate to the head.

4. A presser head attachment for movable head pressing machinescomprising a plate having upwardly extending resilient portions adaptedto engage the head, and a. resilient member cooperatlng with saidupwardly extending portions and extending over the top of the head.

5. The combination of a pressing machine including cooperating heads onemovable relative to the other, one of said heads being formed tonormally permit the escape of steam through its face, and an attachmentinstalled to prevent said escape of steam, said attachment being in theform of a plate adapted to be introduced between the heads andsubstantially co-extensive with the efl'ective pressing areatherebetween, and securing means formed and adapted to pass transverselyover the edges of the head when the plate is moved in a facewisedirection against said head.

6. A presser head attachment for movable head pressing machinescomprising a plate having upwardly extending securing members includingspring held gripping portions, and handle means connected to the membersand extending outwardly from one end of said plate adapted to be graspedto force said members apart in applying or removing the plate to or fromthe head.

In testimony whereof I hereunto aflix my signature.

ROBERT E. GREEN.
